> n_lastn n = reverse . take n . reverse
Which is the most elegant definition, but it's an O(length list) space
operation (as are all others proposed so far). T
No!. You forget laziness!. it is 0(n) with n= the parameter passed to n_lastn.
It is not O(length list).
the reversed and de-reversed elements are just the ones being taken , not the whole list.
